SHUT

Application. vfiler pril. ,5,

For a proper understanding; of the principal obj ect, of. thisinvention it is first neces-, saryto consider, that there are two general classesiof looms now. in use,,itwit, commonly. a; knowna-s automatic and non automatic. It is next necessary to recall that in the automaticloom the shuttle is threaded by entry of the weft or filling sidewise of itself into" the tensioning means of the shuttle, whereas winthe non-automatic shuttle the tensioning;

* means is threaded by entry of the filling lengthwise, of itself, as by a threadinghoolr, Itis finally necessary to recognize that tensioning means of the first type haStnQtjl/S yet been so devised that'it can be reliably u with maintenance ofthe proper tension and without undue breakage of fillin-g, on all kinds of filling. 'l/Yhere certain silk-onother delicate fabrics are being woven, for ex; at: p s ch ension ng means has qu te. limitedpossiloilities of 's uccessfuluse'.

If, then, a manufacturerhas some looms of the antomatictype andsome of'the non-auto matic type he cannot, usefshuttles adapted for the automatic looms in looms of'the, nonautomatic type if, in: the. la ter. looms he Wishes to weavejfabrics whose qua ty, eq ires that the filling, thereof be subject to ensiioning means oft'he. second type, 6011- sequently each class of looms has its own equipment. of shuttles, one with (one and the other with the other type of." tensicning, means, But there are notonlytwo stocks f shuttlesythere. must also be two stocks of" quills to suit them (with the; addition 1" e2 pense of windingbo h s cks. f'quill as w ll, now appear In an automatic o m, shuttle. the. qu lllis 'heldflin place therein y the mere grip of two stoutgripping jaws acting upon thebutt ofjthel quilliand into and out of the grip of which the quill is moved by the transverse thrustwise action of a suffi'ciently powerful; instrun ent a'lity of the loom. In a non autornatic loom shuttle the quillijs bored'and telescoped'onto a spindle which is pivoted at its buttso that itmay be shifted," pivotally, -to projecting relation to theshuttle for receiving or deliveringthe: quill'by hand.

Given, then, a weaving plant having the two A classes of" looms and-desiring tohave one, stock of quills and'suchusable in the shutties of both classes of loomscwinterchangeably, whereby to eliminate the, expense of two stocks of quillscand the duplicate winding thereof, my principal object is to provide a non-automatic loom shuttle which will re? ceive andlproperly. hold a. bored quill suited to shuttles for automatic looms and into or from which the, weavercan without special exertionror fatigue introduce .or remove a quilll. Other objects will appear herein after. r i

The drawings show two forms'of a shuttle embodyingthe invention, Figsl to 4: one form and F 5 to 8 the other. 7 .7 i Fig. 11 is a planofone form, partly in sec-I tiong a is 'fFig. a longitudinal vertical'sectjion there .7 I V 1 Fig, 3a plan of'the clip B 1g; 4; a lsideelevational of'the tongue;

parallel and spaced from each other but appreciably closer together than their free or. quill-gripping portions 5a. Between the portions 56 of thejaws and projecting into the space between their quill-gripping portions 5a is a flat metal tongue 6 which is pivoted to portions .56 at 7. The trifurcate or three-pronged clipt-hus formed is entered to the mortise, vhich it snugly fits, and under its overhangs an from the cavity 2, and it is held in place by what I term two pins Sand 9, one of which, as 8, may be a plain-pin and r the other, 9', a screw or bolt equipped with a nut 9a, they being driven through the shuttle body and clip transversely. When'pi'n 9 is removed the tongue may be elevated on its pivot tothe dotted-line position in'Fig. 2, and for'this purpose whereas the aperture: therein for pin 9 is a hole 11 the aperture for pin 8 is a rearwardly open notch 10. At the free endof the tongue is. pivoted on a removable pin l2a the forked butt of the spindle 12.

. The bored quill is adapted to be slipped, telescopically, onto. this spindle when the latter'is raised (dotted lines,Fig. and when the spindle with the quill thereon is depressed the quill is confined both againstendwise movement on the spindle and against rise pivotally withthe spindle by the gripping action of the jaws of the clip; Notwithstanding the'strong gripping action of the jaws. to prevent inadvertent movementof the spindle whensheathed ordepressed in the cavity and when the shuttle is in action, due to the lever-nature of the spindle the elevating or depressing thereof to clear the quill from or force it between the aws can be man ually effected by the weaver with ease.

On removalof pin .9 and elevation of tongue 6 so that it projects from thespace of the fixed shuttle structure with its pin 12a clear the pin (which is otherwise confined between the jaws of the clip) may be removed to change thespindlel The forward lower corner of the tongue and the floor of the mortise afford a stop to the spindle on depressing the same (Fig. 3). Figs. 5to 8: f I i If in some instances, as in large shuttles carrying heavy quill loads, it is desired to augment the gripping. action of the jaws against possiblerise of the spindle, a platespring 13 may be employed. Thisis formed.

to fita recess 14: at the top of the mortise and it bears at one" end on theshuttle body and at the other end on the spindle butt,being held down under adjustable pressure between its cops or other wound cores to be used in the shuttle which are too small at the butt to be gripped by the jaws 5 so that the spindle.

when the shuttle is in use would be held depressed by their gripping action.

Having thus fully described my invention what I claim is: I

1. In combination, a shuttle body havinga space therein open at one longitudinal face thereof, a trifurcate structure'held in said body and having its prongs in said space and the two outer prongs onopposite sides; of a This spring serves effectiveplane extending lengthwise of the shuttle and through said face and forming wound-coregripping jaws, and a spindle pivoted at its butt to the intermediate prong to move in said plane into and out of said space and into and out of position where acore therein will be gripped by the jaws.

2. In combination, a shuttle body having a space therein open at one longitudinal face thereof, avpair of fixed members in said body having spaced wound-core-gripping jaws in, said space and on opposite sides of a plane: extending; lengthwise of the shuttle and:

through said face, a tongue heldbetween said members, and a spindle pivoted at its butt tothe tongue to move in said plane into and out of said space and into and out, of positionwhere' a core thereon will be gripped by the jaws.- s V 3. In combination,the fixed structure of a shuttle, said structure having a space there'- in open at one longitudinal face thereof, a

tonguev arrangedin said structure and hav-' ing a portion thereof'inj said space, and a spindle pivoted to said portion of the tongue to move in a plane extending lengthwise of the shuttle and through said face, said tongue being movable in said: structure to bring its said portion exterior of said space'bu't nor-[ mally releasably held against such movement, and the spindle being disconnective from said tongue when said portion thereof is exterior" of said space but being confined by saidstruc ture against disconnectionfrom the tongue when said portion is within said space.

4. In combination, the fixed structure of a shuttle, said structure having a spaceth'erein open at one longitudinal face thereof," a

tongue arranged'in said structure and having a portion thereofin said space, and aspindle I.

pivotedto said portion of the tongue to move in a plane extending lengthwise of the shuttle V and through said'face, said tongue being pivotally movablein's'aid structure to bring its 136 said portion exterior of said space but normally releasably held against such movement and the spindle being disconnective from said tongue when said portion thereof is exterior of said space but being confined by said structure against disconnection from the tongue when said portion is within said space.

5. In combination, a shuttle body having a wound-package cavity open at one longitudinal face thereof, wound-package-holding means secured in said body and including coacting package-gripping portions projecting into said cavity on opposite sides of a. plane extending lengthwise of the shuttle and through said face, a spindle on which a wound package is adapted to be telescopically placed pivotally movable in said plane, either into sheathed position in the cavity or into position to project therefrom, and means in the cavity affording pivotal support for this spindle.

6. In combination, the fixed structure of a shuttle, said structure having a Woundpackage cavity open at one longitudinal face thereof and spaced means to grip a wound package when placed within the cavity and arranged on opposite sides of a plane extending lengthwise of the shuttle and through said face, and a spindle on which the package is to be telescopically placed arranged in said cavity with its butt between and spaced from said means, the spindle being pivoted to said structure to move in said plane either into sheathed position in the cavity or into position to project therefrom.

In testimony whereof I affix my signature.
